About Converting Rods to Inches
Rod and Inch both measure length. Specifically: A rod is 16.5 feet, and an inch is exactly 0.0254 meters.
Formula
inches = rods × 198
This factor comes from each unit's defined relationship to the category's base unit: 1 rod equals 5.0292 base units, and 1 inch equals 0.0254 base units, so dividing one by the other gives the direct rod-to-inch factor of 198.
Simple example
1 rd × 198 = 198 in
1 rod = 198 inches.
Real-world example
10 rd × 198 = 1,980 in
10 rods = 1,980 inches.
